Hyperscale Firewall Guide

Enabling or disabling the NP7 VLAN lookup cache

You can use the following command to enable or disable VLAN lookup (SPV/TPV) caching for hyperscale firewall sessions.

config system npu

set vlan-lookup-cache {disable | enable}

end

This option is enabled by default.

Due to a known issue, with hyperscale firewall enabled, this option should be disabled if you configure more than 256 VLANs. Enabling or disabling vlan-lookup-cache requires a system restart. So you should only change this setting during a maintenance window.
